Go half and half with a player on his buy-in to a game; usually preceded by
go; sometimes followed by up.
When the player quits, he splits with the person with whom he went cow. Sometimes
the house goes cow
with a player to enable him to get into a larger game than he could otherwise
afford, generally with the no altruistic
purpose of filling what would otherwise be a shaky game. At some point when
the player (the house hopes) gets far
enough ahead of the game, the house may split him out, that is, remove half
of his chips and put him on his own.
